How did the Fund perform during the reporting period? 

It is remarkable to think back to all the major storylines that played out this year. The 2nd quarter was particularly eventful, starting with “Liberation Day” on April 2 and ending with the War between Israel and Iran. In the end, we saw the bear turn into a bull. Markets had a strong first half, and the TOPS portfolios were particularly boosted by a memorable rally in international stocks.

 

Year-to-date, large-cap growth (S&P 500 Growth Total Return Index) has risen +8.9%. Large-cap value (S&P 500 Value Total Return Index) is up +3.3%. Mid-cap equities (S&P MidCap 400 Total Return Index) are slightly positive at +0.2%, while small caps (S&P Small Cap 600 Total Return Index) continue to lag, down -4.5%. Developed international markets (FTSE Developed ex US All Cap Net Tax [US RIC] Index) are leading globally, up +20.0%. Emerging markets ex-China (MSCI Emerging Markets ex-China Net Return USD Index) are up +14.5%, and emerging markets ex-state-owned enterprises (WisdomTree Emerging Markets ex-State Owned Enterprises Index) have gained +11.4%. Broad-based emerging markets (FTSE Emerging Markets All Cap China A Inclusion Net Tax [US RIC] Index) are also up +11.2%. Emerging market local currency bonds (J.P. Morgan Government Bond Index Emerging Markets Global Core) are up +12.0%, high-yield corporate bonds (Solactive USD High Yield Corporates Index) have risen +4.8%, and intermediate-term Treasuries (Bloomberg U.S. Treasury 3-10 Year Total Return Index) are up +4.8%. Corporate bonds (ICE BofA US Corporate Index) gained +4.2%, while mortgage-backed securities (Bloomberg US MBS Float Adjusted Index) returned +4.2%. Short-term TIPS (Bloomberg US Treasury TIPS 0-5 Years Index) and short-term Treasuries (Bloomberg U.S. Treasury 1-3 Year Index) rose +4.0% and +2.8%, respectively. Global ex-US aggregate bonds (Bloomberg GLA xUSD Float Adjusted RIC Capped Index) are up +1.8%. Global natural resources (Morningstar Global Upstream Natural Resources Net Return Index) are up +11.9%. Global real estate (FTSE EPRA NAREIT Global REITs Net Tax Index) has also advanced, gaining +4.1%.

How did the Fund perform during the reporting period? 

It is remarkable to think back to all the major storylines that played out this year. The 2nd quarter was particularly eventful, starting with “Liberation Day” on April 2 and ending with the War between Israel and Iran. In the end, we saw the bear turn into a bull. Markets had a strong first half, and the TOPS portfolios were particularly boosted by a memorable rally in international stocks.

 

Year-to-date, large-cap growth (S&P 500 Growth Total Return Index) has risen +8.9%. Large-cap value (S&P 500 Value Total Return Index) is up +3.3%. Mid-cap equities (S&P MidCap 400 Total Return Index) are slightly positive at +0.2%, while small caps (S&P Small Cap 600 Total Return Index) continue to lag, down -4.5%.

How did the Fund perform during the reporting period? 

It is remarkable to think back to all the major storylines that played out this year. The 2nd quarter was particularly eventful, starting with “Liberation Day” on April 2 and ending with the War between Israel and Iran. In the end, we saw the bear turn into a bull. Markets had a strong first half, and the TOPS portfolios were particularly boosted by a memorable rally in international stocks.

 

Year-to-date, large-cap growth (S&P 500 Growth Total Return Index) has risen +8.9%. Large-cap value (S&P 500 Value Total Return Index) is up +3.3%. Mid-cap equities (S&P MidCap 400 Total Return Index) are slightly positive at +0.2%, while small caps (S&P Small Cap 600 Total Return Index) continue to lag, down -4.5%.

How did the Fund perform during the reporting period? 

It is remarkable to think back to all the major storylines that played out this year. The 2nd quarter was particularly eventful, starting with “Liberation Day” on April 2 and ending with the War between Israel and Iran. In the end, we saw the bear turn into a bull. Markets had a strong first half, and the TOPS portfolios were particularly boosted by a memorable rally in international stocks.

Mid-cap equities (S&P MidCap 400 Total Return Index) are slightly positive at +0.2%, while small caps (S&P Small Cap 600 Total Return Index) continue to lag, down -4.5%.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period? 

It is remarkable to think back to all the major storylines that played out this year. The 2nd quarter was particularly eventful, starting with “Liberation Day” on April 2 and ending with the War between Israel and Iran. In the end, we saw the bear turn into a bull. Markets had a strong first half, and the TOPS portfolios were particularly boosted by a memorable rally in international stocks.
